If you spot such things, then it is best to spray any bacteria-resistant pesticide on the tree.

The leaf scorch disease occurs as an outburst of the weather stress, i.e., extreme and sudden change in the weather. Hence, it generally appears after a really dry and hot weather. It occurs as the tree roots cannot supply the adequate amount of water to the leaves. In case of this disease, it is very important to make sure that there is enough of the soil moisture around the tree. Mulching around the tree and wetting the soil can be very helpful for the plant to maintain its health. Also, make sure that the roots of the tree don’t get damaged by the lawn movers and string trimmers.

The spots have grayish-white centers that are defined with sharp margins. If not treated in time, the margins get swelled up and can cause bumpy structures on the leaves. On initial spotting of the disease, it can be managed by spraying regular fungicides.
- Root Rot Disease:
Root rot disease on ornamental pear trees is caused by fungal infection. This disease is also known as cotton root rot. The foremost symptom of this problem is wilting of the leaves in the summer season, when this fungus is most active. If not checked in time, the tree can die with the healthy leaves still on the trees. This disease mostly affects the matured trees and can also cause rotting of the entire tap root. This problem can also be caused by poor irrigation. So, it is very important to provide the plant with proper irrigation and quality fungicides.
